Rob Porter speaking to President Trump on Aug. 12.

Now that Rob Porter is out of the White House, he joins a list of alleged domestic and sexual abusers whom President Trump has staunchly defended.

Porter abruptly stepped down from his staff secretary post Thursday amid allegations that he abused his two ex-wives, culminating in a shocking photo that one of the former spouses produced of her face battered and swollen after an alleged beating.

"We hope he has a wonderful career and hopefully he will have a great career ahead of him," Trump told reporters. "He also as you probably know says he is innocent and I think you have to remember that. He said very strongly yesterday that he is innocent."

"The people of Alabama will do the right thing," Trump tweeted on the state's election eve. "Roy Moore will always vote with us. VOTE ROY MOORE!"

Trump didn't bother addressing claims that Moore had tried to have sex with a 14-year-old girl, sexually assaulted a 16-year-old and pursued a number of relationships with teenagers while he was in his 30s. For, just like Porter, Moore had denied the allegations against him.

"(Trump) thinks the people of Alabama should make the decision on who their next senator should be," Press Secretary Sarah Huckabee Sanders said, adding that Moore should "step aside" only if the allegations are true.

But even though he denied the allegations, extensive reporting by the Washington Post and other outlets unearthed plenty of credible evidence and testimony that Moore had actually harassed and molested young girls.

Bannon grabbed his wife's wrist and neck and tried to force her into a car after they got into an argument, according to a police report. The charges ended up getting thrown out after his wife failed to show up for court.

But Trump evidently didn't find the allegations against Bannon all that concerning, since he kept him on as his campaign CEO, despite damning media reports about the alleged domestic assault incident. After the election, Trump appointed Bannon as his chief strategist, lauding him as "efficient, effective and productive."

Just like Moore and Porter, Bannon denied the allegations against him.

It seems like it was eons ago when Trump tapped Andrew Puzder, the CEO of the CKE fast food corporation, as his nominee for Labor Secretary.

Puzder's nomination drew outrage because he had a long history of opposing any and all efforts to increase the federal minimum wage. But those concerns paled after it was revealed that Puzder had assaulted his ex-wife in the 1980s.

"(Puzder) attacked me, choked me, threw me to the floor, hit me in the head, pushed his knees into my chest, twisted my arm and dragged me on the floor, threw me against a wall, tried to stop my call to 911 and kicked me in the lower back," Puzder's ex, Lisa Henning, told a St. Louis newspaper in 1989.

Trump ended up not having to defend Puzder because he withdrew his Labor czar nomination shortly after the allegations resurfaced.

But, according to recent reports, Trump and his advisers are looking at options to find another White House position for Puzder, especially one that wouldn't need Senate confirmation.

Puzder, like Moore, Porter and Bannon, has denied all the allegations against him.

Looking out for number one.

Trump evidently has a penchant for standing by those in his midst who have been accused of sexual or domestic abuse, but it would be a big miss to not mention the fact that the person Trump stands most steadfastly by is himself.

The President's ex-wife Ivana Trump accused him of assaulting and raping her, according to a 1990 divorce deposition.

The legal papers describe how Trump ripped out handfuls of his wife's hair before raping her in what was described as "a violent assault."

Ivana ended up recanting those shocking claims after the deposition resurfaced in news reports during the campaign. "The story is totally without merit," Ivana said in a statement responding to the disturbing court papers. "Donald and I are the best of friends and together have raised three children that we love and are very proud of."
